plz, answer all questions clearly and correctly. i am begging you 6. If the half-life for decomposition of a drug is 12 hours, how long will it take for 125 mg of Mathematical Fundamentals in Pharmacokinetics 41 the drug to decompose by 30%? Assume first- order kinetics and constant temperature.
Methamphetamine has a biological half life of about 20 hours. How will it take (in hours) to have 90% of the meth cleared from a drug addict? Assume first order kinetics
Drug A has a Clearance of S.6 /hr and a half-life of 12 hours. Calculate the volume of distribution in Liters (round to the nearest integer number)
16. Suppose that the allergy drug, Sneezebgone, has a half life of 12 hours and is excreted at a rate that is proportional to the amount present. At 8am, Declan takes one 10 mg dose of Sneezebgone, and then another 10mg dose at 8pm. Assuming that the drug is given intravenously via injection and mixed into his bloodstream immediately) how many mg of sneezebgone are in his system at midnight?
